60 STBUCTURE OF THE LEPIDOPTEBA 



have received one ; but the scientific names will always be given 

 as well for the benefit of those readers who would like to know 

 them. And the short description of the method of classification 

 just given will enable the more ambitious of my readers to tho- 

 roughly understand the table of British butterflies and moths 

 toward the end of the book. 



This table includes all the British species of butterflies and of 

 the larger moths ; and the arrangement is such as to show clearly 

 the divisions into sections, families, &c. It will therefore be of 

 great value for reference, and as a guide for the arrangement of 

 the specimens in the cabinet. 



In the foregoing description of the method of classification 

 butterflies only are mentioned ; but the division and arrangement 

 of moths is carried out in just the same manner except that the 

 system is a little more complicated. The number of moths is so 

 large in comparison, that we are able to select from them some 

 very large groixps the species of which possess features in common. 

 These groups are termed tribes, and are again divided into families 

 just like the butterflies. Thus the arrangement of moths includes 

 tribes, families, genera and species. We will take an example by 

 way of illustration as we did before, and ask the reader to verify 

 the same by comparison with our table :

I have already said that the Latin and Greek names of butter- 

 flies and moths are not at all necessary to the young entomologist. 

 It is quite possible to be well acquainted with the natural history 

 of these creatures, and to derive all the pleasure and benefits that 

 the study of them can afford without the knowledge of such names ; 

 but most entomologists go in for them, often to the entire exclusion 

 of the popiilar English terms. 



There are those who consider themselves (or would have us 

 consider them) expert entomologists because they have the power
